Product Description
Soybean oil is a type of soybean oil that contains high amounts of linoleic acid.Linoleic acid is an essential fatty acid with important physiological functions.Children lack of linoleic acid, the skin becomes dry, scale thickening, growth retardation;Elderly lack linoleic acid, can cause cataract and cardiovascular cerebrovascular disease.
The fishiness of soybean oil is caused by linolenic acid and isolinoleic acid, and the "aftertaste" of soybean oil can be eliminated by the method of selective hydrogenation to minimize the content of linolenic acid and avoid the formation of isolinoleic acid.Refined soybean oil changes color from light to dark when stored for a long time, a phenomenon called "color restoration."
The color restoration of crudely pressed soybean oil is more remarkable than that of other oils, and the complex changes caused by the automatic oxidation of oils may be the basic reason.This phenomenon can be prevented by reducing the moisture content of raw materials. This method is widely used, which basically solves the color of soybean oil.
In addition to fat, some non-oil substances are brought into the crudely processed soybean oil. In the unrefined crude oil, there are 1%-3% phospholipids, 0.7%-0.8% sterols, a small amount of proteins and wheat germ phenol, etc., which can easily cause rancidity. Therefore, if the impurities are not removed by hydration, the soybean oil is not suitable for long-term storage.
Summary of oil yield of common oil crops;Oil yield refers to the amount of oil per oil plant when peanut, soybean and other oil crops are pressed for oil. The calculation formula is: oil yield = oil weight ÷ (total weight - impurity removal weight) ×100%.
A, soybeans,
Soybean is a kind of high quality protein oil crop, oil content of 15%-26%, oil yield: according to different soybean quality in different places 12%-18% (imported soybean oil yield is higher than domestic oil yield)
Two, rapeseed
Rapeseed (rapeseed flower) is the only high oil content oil that can be grown all over the world. It comes in two varieties: winter rape and spring rape.In China, its planting area accounts for more than 40% of the total area of oil crops, with oil content of 35%-50%.Oil yield: 30%-45% according to different rapeseed quality
Third, cottonseed
Cottonseed, as the name implies, is the seed of cotton. The whole seed of cottonseed contains 15%-25% oil, and the kernel contains 28%-39% oil.
Oil yield: according to different quality of cotton seed 11%-25%
Four, peanuts,
The original name of groundnut, originated in South America, peanut kernel rate is 65-75%, peanut kernel oil 40%-51%, oil yield: according to the quality of different 40%-50%
Sunflower seeds
Originated in Mexico, it is divided into edible sunflower (sunflower seeds) and oil sunflower.Oil sunflower is mostly small black seeds, and the oil content of the whole seeds is as high as 45%-54%, so oil sunflower is mainly used for oil extraction. Oil yield of sunflower seeds (oil sunflower) is 32%-42% according to different quality in different places
6. Sesame (flax seed)
Sesame, also known as sesame, flax, is the seed of flax, oil content of 45%-63%, the queen of oil said;Sesame oil is one of the few vegetable oils that can be eaten without refining.Sesame (flax) oil yield: according to the quality of different 45%-55%
Seven, rice bran
Rice bran is a by-product of rice processing. Every 100 kg of brown rice processed can produce 5-8 kg of rice bran.Rice bran oil content of 14%-24%;Rice bran oil yield: 13%-17% according to different quality
Eight, camellia oil seed
Camellia seed is the seed of the camellia tree (Camellia oleifera);Camellia is mainly grown in the south of our country.Camellia seed with shell, containing kernel rate of 50%-72%, camellia seed oil of 30%-40%, camellia seed oil yield: according to the quality of different 14%-27%
Oil palm fruit (palm fruit)
Oil palm fruit also known as palm fruit;45%~50% oil, originally produced in Africa, but now has been all over the world;Palm oil is currently the world's largest production, consumption and international trade of vegetable oil varieties, and soybean oil, rapeseed oil and known as the "world's three major vegetable oil" oil yield rate: according to different quality around 20%-22% crude palm oil, palm kernel oil about 2%;
The actual pressing is also related to the equipment process used by oil crops and the pressing process (hot pressing or cold pressing). Generally speaking, taking peanuts as an example, the higher the pressing pressure, the lower the slag content, the lower the residual oil ratio of dry cake and the higher the oil yield
